Electric WH - no heat?
Changed out an electric WH that stopped producing hot water ... Intsalled a new GE model ... 50 gallons, 220VAC, 30A circuit.

All connections done -- it has water. Checked for live circuit, proper ground.
Checked for current at the block inside the WH ... it is live.

NO HEAT being generated.

Ideas?? I am stumped ...

Both wires have 120 volts to ground? One side of a double breaker not working?

What about an adjustable thermostat set low? Just a thought. And did you try pushing the reset button?

Thanks guys ... I set the thermostat to 135 by adjusting the set screw. Located and pushed the reset button, although there was no light (is there a light behind the button?).

I am going to check the lines with a clamp meter to check voltage on each leg. However, I did register current with a tickler on both sides PLUS I checked for current at the wiring block inside the WH and it was live on both sides.

You needed to check both wires before the switch was connected or turned on.

Thanks, Neal ... Before wiring the WH, I did check the separate wires for the presence of current but I did NOT curck with the clamp meter for voltage. That is where I am starting.

However, one would expect SOME kind of heating even with only 1/2 of the power present in the unit. The hetaing elements would be under-charged but producing some heat ...

If you have power on both, and no heat the upper element or upper thermistat may have a problem. What was wrong with the old tank?

Sorry for the delay guys ... I do not work on Sunday.
I will be after it at 0600 tomorrow and on the line with the service techs. Will let you know how it turns out ...

Stand by ... News at 11:00PM or sometime Monday.

You need to check the voltage wire to wire, not wire to ground. You could get voltage from each wire to ground and still not have 240 volts.
